CORRUGATED-METAL CULVERT.

Patented March 17, 1908.

Application filed August 27, 1907, Serial No. 390,311.

To all whom it may concern:

Be it knownthat I, J ULIUs H. SCHLAFLY, a citizen of the United States, residingat Canton, in the county of Stark and State of Ohio, have invented a new and useful Corru gated-Metal Culvert, of which the following is a specification.

.. My invent on has for its objectto provide "a corrufatedf sheet metal pipe especially designs for use as a culvert, ut it will be understood that it may be applied to other uses, without departing from the nature of the invention.

A further object of the present invention is to so form the members going to make u the culvert that they can be nested an shipped from the factory ina nested condition, thereby reducing the bulk during'transrtation and at the same time allowing a liii e number of the members of the sections to be stored in warehouses.

In the drawing, Figure 1 is a perspective view showin a number of members connected (I one member detached. Fig. 2 is a view showing a number of culvert members nested. Fi 3 is aside elevation showin a portion of t e culvert proper in section.-

imilar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawings, 1, re resent the culvert members or sections, w rich may be of any desired length and size, which members or sections are formed. substantially' as shown in the drawings, and each section or member constituting one-half of the circumference of the culvert proper. The sections "or members are each provided with the lateral flanges 2, which flanges are for the purpose of providin means for connecting the members toget er so as to produce a cylindrical pi e. I

For the' purpose 0 increasing the rigldit of the members'and the finished pipe or on vert, thereby preventing an crushing of the metal constituting the cu vert when the same is placedin position for use the various members or sections are corrugated and when the members are connected together at their flanged sides by means of the clamping bolts or rivets 3 the corrugation Wlll be circumferential. The flanges 2 are corrugated, which corrugations are in alinement with the corrugations formed in the segmental members or sections. By corrugating the flanges the various sections or members are easily assembled by simply lapping the adjacent ends of the members or sections. In use I prefer to lap one corrugation over each adjacent member ,or section as-illustrated in Fig. 3. In some instances it may bedesired to rivet the lap ends together, but I do not desire to be confined to this s ecific manner of connecting the ends toget er, owing. to the fact that proper] lapped and connected.

It wi 1 be understood that the corrugated flanges assist in preventing any relative movement as between what might be opposite mem ers of the culvert proper. In use the transverse joints or the jomts connected at the adjacent ends of the culvert'members or sections should be alternated that is to say the joint should not be entirel circumferential, but each joint should be lbcated about midway between the ends of the member or section to which the jointed sections'are attached. By providing the lateral flanges and connecting them together the difl'erent members constitutingthe culvert proper, that is to say opposite members come and go at their junctions with the maindmdies of the culvert sections thereby providing for a limited expansion without injury to the metal.

Having fully described my invention what I claim as new and desire to secure by Let-v ters Patent, is

1. As an improved article of manufacture, a culvert section or member constructed of metal and provided with corrugations, flanges provided with corrugations corretlons or members, substantially as and for the purpose specified.

tions, said sections or members provided with lateral flanges and the flanges adapted to be connected together and the sections there can be no displacement of the mem' bers or'sectlons after the flanges 2 have been termed the u )per and lower members or.

2. A culvert consisting .of a series of sec.-

.sponding with the corrugations of the secprovided with circumferential corrugations, 1siublstantially as and for the purpose speci- 3. A culvert consisting of sections, each section provided with lateral flanges and the flanges adapted to be connected together and the sections provided with corrugations, substantially as and for the purpose specified.

In testimony that I claim the above, I have hereunto subscribed my namein the 1( presence of two witnesses.
